1. Take the Seat Rail Mounting Bracket Base Plate and match its slope to the slope of your bicycle's seat rail.
2. Attach the Seat Rail Mounting Bracket Panel, raising one end upwards to align with the base plate.
3. Insert the screws into the slots, interchanging left and right as needed. For carbon fiber seat rails, apply a torque of approximately 4N·m to avoid damage.
4. Adjust the angle of the mount and tighten the screws securely.
5. Install the Lanyard onto the main unit and then attach the Radar Tail Light L7 main unit to the mount. Ensure the lanyard is installed to prevent the tail light from being lost.
6. Verify that the tail light's base remains perpendicular to the ground to ensure accurate radar detection.

3.4. Mounting to Seatpost

1. Select the appropriate rubber pad (Seat Post Rubber Pad 1 for O-shaped/round seatposts, Seat Post Rubber Pad 2 for D-shaped/aero-shaped seatposts) based on your seatpost's shape.
2. Secure the chosen rubber pad and the mounting bracket to your seatpost using either the Long Rubber Strap or Short Rubber Strap, ensuring it is tight and stable.
3. Install the Lanyard onto the main unit and then attach the Radar Tail Light L7 main unit to the mount. Ensure the lanyard is installed to prevent the tail light from being lost.
4. Verify that the tail light's base remains perpendicular to the ground to ensure accurate radar detection.

4. Operating Instructions

4.1. Power On/Off

Short press the button on the body of the tail light to cycle through the following modes:

• Constant Mode 1: Steady light, suitable for various riding scenarios.
• Constant Mode 2: Another steady light option.
• Blinking Mode: Flashing light, suitable for solo night rides.
• Breathing Mode: Soft, pulsating light, suitable for nighttime leisure or group rides.
• Radar Mode: Optimized for daytime riding, focusing on radar detection with appropriate lighting.
• Off Mode: Turns off the light.

4.3. Intelligent Sensing Features

• Automatic Sleep and Wake-up: The device automatically enters sleep mode after 3 minutes of inactivity and wakes up upon detecting movement.
• Automatic Brake Sensing: When braking is detected, the tail light will highlight for 2 seconds to alert following traffic. This feature is active in all modes except Blinking and Breathing modes.

4.4. Radar Functionality

Multi-Use Indicator Light:

4.6. Peloton Mode

During group rides, when multiple L7 tail lights are set to the same flashing or breathing mode and are within a certain distance, they can synchronize their flashing frequencies. This helps maintain group cohesion and visibility.

5. Maintenance

• Cleaning: Wipe the device with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Water Resistance: The L7 is IPX6 water-resistant, meaning it can withstand strong jets of water. However, it is not designed for submersion. Ensure the charging port cover is securely closed to maintain water resistance.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the device regularly, especially if it will be stored for an extended period.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures (-10°C to 75°C).

6. Troubleshooting

6.1. Device Not Turning On

• Ensure the battery is charged. Connect the device to a power source using the USB Type-C cable.
• Long press the power button to turn on the device.

6.2. Radar Not Detecting Vehicles

• Ensure the tail light is mounted vertically to the ground. Incorrect orientation can affect radar performance.
• Check if the radar function is enabled via the CYCPLUS app or your connected bike computer. The inner indicator light should be constant on when radar is enabled.
• Ensure there are no obstructions blocking the radar sensor.

6.3. Connectivity Issues (ANT+/Bluetooth)

• Ensure the L7 is powered on and within range of your bike computer or smartphone.
• On your bike computer or app, go to the sensor settings and select 'Radar' or 'Lights' to search for the device.
• If using a bike computer, ensure it is one of the compatible models (Wahoo ROAM V2, BOLIT V2, ACE; Garmin 830, 1030, 840, 1040, 1050, and explore).
• Try restarting both the L7 and the connecting device.

6.4. Light Modes Not Changing

• Short press the button firmly to cycle through modes.
• If using the app, ensure the app is connected and changes are being applied.

8. User Tips

• Optimal Radar Performance: Always ensure the tail light is mounted vertically to the ground. This is crucial for the radar to accurately detect objects and avoid false readings.
• Lanyard Use: For added security, always install and use the provided lanyard to prevent accidental loss of the tail light during rides.
• Carbon Fiber Seat Rails: When installing on carbon fiber seat rails, be mindful of the torque. Overtightening can damage the seat rail. A torque of approximately 4N·m is recommended.
• App Configuration: For Android users, the official CYCPLUS app can be used to configure radar mode settings and adjust light brightness, offering more control over your device.
• Compatibility Check: While the L7 supports ANT+ and Bluetooth, always verify compatibility with your specific bike computer model if it's not explicitly listed as supported (e.g., Polar v650, Garmin 64um, Magene C508, Cycplus M1).
